The Sheet Metal and Air Conditioning Contractors’ National Association now offers members a smart phone application on duct air leakage.

The free app is available through Apple’s iTunes Store and works on iPhones, the iPad and the iPod Touch. It uses information from SMACNA’s latest version of the HVAC Air Duct Leakage Test Manual.

It is a quick way to determine the pass-fail mark for specified leak tests, association officials said. The application also creates a report that can be e-mailed.

For details and the application, go to the iTunes Store and search for “SMACNA.”
